Nginx動靜分離+快取

#進入Nginx應用目錄 
cd /etc/nginx/

#備份原nginx.conf檔案 
mv  nginx.conf  nginx.bak  

建立 vi nginx.conf ，並寫入如下內容:
user www www; 
worker_processes 8; 
worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;

###2012-12-19 change nginx logs 
 
log_format  main  '$http_x_forwarded_for - $remote_user [$time_local] "$request" ' 
              '$status $body_bytes_sent "$http_referer" ' 
              '"$http_user_agent"  $request_time $remote_addr'; 
 
#這裡為後端伺服器wugk應用叢集配置，根據後端實際情況修改即可，tdt_wugk為負載均衡名稱，可以任意指定
#但必須跟vhosts.conf虛擬主機的pass段一致，否則不能轉發後端的請求。
upstream tdt_wugk { 
    server   10.10.141.30:8080 weight=1 max_fails=2 fail_timeout=30s; 
    server   10.10.141.30:8081 weight=1 max_fails=2 fail_timeout=30s;

} 
#include引用vhosts.conf，該檔案主要用於配置Nginx 虛擬主機  
include vhosts.conf; 
} 
   如上nginx.conf配置完畢,繼續配置nginx虛擬主機，繼續在當前目錄建立vhosts.conf

  vi vhosts.conf 內容如下：
####www.wuguangke.cn

  { 
    listen       80; 
    server_name  www.wuguangke.cn;

         proxy_pass http://tdt_wugk; 
         expires      3d; 
    } 
    #動態頁面交給http://tdt_wugk，也即我們之前在nginx.conf定義的upstream tdt_wugk 均衡 
    location ~ .*\.(php|jsp|cgi)?$ 
    { 
         proxy_set_header Host  $host; 
         proxy_set_header X-Real-IP $remote_addr; 
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
         proxy_pass http://tdt_wugk; 
    } 
    #配置Nginx動靜分離，定義的靜態頁面直接從Nginx釋出目錄讀取。
    location ~ .*\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css)$ 
    { 
    root /data/www/wugk; 
#expires定義使用者瀏覽器快取的時間為3天，如果靜態頁面不常更新，可以設定更長，這樣可以節省頻寬和緩解伺服器的壓力
    expires      3d; 
    } 
    #定義Nginx輸出日誌的路徑 
    access_log  /data/logs/nginx_wugk/access.log main; 
    error_log   /data/logs/nginx_wugk/error.log  crit; 
}
